PowerQuest's (now owned by Symantec) Drive Image SE allowed
Compaq to create a sector-by-sector compressed
image of the original factory state of a hard drive (on the hard drive or on a CD) and
also allowed end-users to create their own user image so that
in the event of system corruption or data corruption
they didn't lose their data, application loads and system preferences that they added
since the purchase of their computer system.

Compaq
sold over 6 million computers a year configured with
PowerQuest's image recovery tools for several years.
PowerQuest gave Compaq just a small subset of its Drive
Image and Partition Magic code to Compaq and made $Millions
on this deal at just 25 cents per unit royalty.
